Family Matters (DiCarlo Brides book 4). The DiCarlo Brides, #4

She's survived a father's demands, a found family of strangers, and a life she never planned. But this time, the stakes are everything. Rosemary Keogh prides herself on being adaptable. When her late father's final wish forced her to uproot her life and work at his newest resort-alongside five half-sisters she barely knew-she rose to the challenge. Slowly, she found her rhythm, even began to care for the family she never asked for.
But nothing prepares her for the day tragedy strikes, and she's named guardian of her nine-year-old birth daughter-a spirited, stubborn child who mirrors Rosemary in all the best (and most exhausting) ways. Just as she begins to navigate motherhood, her life takes a darker turn: mysterious accidents start piling up, and it becomes clear someone wants her out of the picture. Harrison Forest, the resort's charming but infuriating head of HR, has always sparked something in Rosemary-even if their interactions have been more sparks and spats than flirtation.
But when danger draws closer, he's suddenly the one person she's not sure she can push away. As secrets unravel and danger circles, Rosemary must protect her daughter, trust her heart, and find out who's behind the threats-before her second chance at family, love, and life is stolen from her for good.
